TURNBUCKLE-WRENCH.

Specification of Letters Patent.

Patented J 11110 29,1920.

Application filed February 17, 1920. Serial No. 359,318.

To all Ti /LOH! it may concern Be it known that I, CARTER J. JoHNsoN, a citizen of the United States, residing at Green Bay, in the county of Brown, State of Wisconsin, have invented certain new and useful Improvements in Turnbucklerenches; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wrenches and particularly to wrenches for operatin turnbuckles.

The principal object or the invention is to provide a novel and improved wrench which is especially adapted for use in connection with the turnbuckles of the. guy wires of aeroplanes, dirigible airships, and the like, and whereby the turnbuckles can be turned in any position.

Another object is to provide a novel and improved wrench of this character by means of which turnbuckles which are disposed close to other parts of the machine, and cannot be easily turned by ordinary tools, can be readily and conveniently operated.

A further object is to provide a novel and improved wrench of this characterwhich can be so connected to the turnbuckle that danger of the wrench slipping is completely obviated.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of a wrench made in accordance with my invention.

Fig. 2 is a front elevation of the same.

Fig. 3 is a vertical longitudinal sectional view taken centrally through the wrench, on the line 33 of Fig. 2.

Fig. 4 is a fragmentary perspective view of the wrench showing its ordinarv operative position with respect to the turnbuckle.

Fig. 5 is a fragmentary perspective view of the wrench showing the opposite end engaged with the turnbuckle.

Fig. 6 is a perspective View of the wrench showing the same with its side pin engaged in the opening of the turnbuckle.

Referring particularly to the accompanying drawing, 10 represents a metal tube of suitable diameter and length, having its opposite ends bifurcated, as shown at 11 and '12, respectively, said bifurcations being arranged at right angles to each other. Disnal' pin '15. One end portion of the pin.

protrudes from the end ofthe plug centrally between the legs of the bifurcation 11. Disposed transversely through the tube and the plug, at a point approximately centrally of the length thereof, is a pin 16 which extends a distance beyond one side of the tube sufficient to readily enter the opening 17 in the turnbuckle nut 18. In the other end of the tube is disposed a short plug 19 having a longitudinal opening or groove in one side, as shown at 20, the inner end of the plug being cut away at 21 and having a leaf spring 23 secured therein. A pin 22 is removably disposed longitudinally in this groove and engages with the free end of the spring to retain itself therein, when not in use. The pin can be readily pulled out upon the use of slight force. In the legs of the bifurcation 12 there are formed openings 24 for alinement with the opposite ends of the opening of the turnbuckle, and through which openings the pin 22 is adapted to be engaged. The pin is formed with a head 22 to prevent passage through the openings. This arrangement of the parts insures the proper and firm engagement of the wrench with the turnbuckle so that it will not become detached therefrom should the operator release his grip of the wrench.

The legs of the bifurcation 11 engage the opposite sides of the turnbuckle and serve as braces while rotating the wrench around with the turnbuckle.

When the side pin is engaged in the opening of the turnbuckle the body of the wrench lies close to and parallel with the turnbuckle, and by grasping both the turnbuckle and wrench in the hand, the operator can readily turn the turnbuckle. This is especially useful in small and confined places where the wrench, as used in the other manners, could only be moved within a small are.

It will be noted that the pin 15 extends practically the entire length of the bore 14, and should the protruding end of the pin break off, a nail, or other suitable means 5 hammer, or the like, drive the pin through the bore so as to expose a new portion for insertion in the opening of the turnbuckle.

What is claimed is: 1. A turnbuckle Wrench including an elongated body having its end bifurcated,

a removable member disposed within the body, a longitudinal pin in the center of the removable member and protruding from one end thereof, said pin being adapted to be driven forward in the removable member to supply new protruding portions.

2. A turnbuckle wrench including an elongated body having its end bifurcated and the legs thereof formed with alining openings, a plug seated in the other end of the body and having a longitudinal groove in one side, a leaf spring secured to the inner end of the plug and extending across the groove, and a removable pin engaged in the groove and held by the spring said pin being adapted to be passed through the openings of the legs of the bifurcation and nut of a turnbuckle.

In testimony whereof, I affix my signature in the presence of two Witnesses. CARTER J. JOHNSON.
